' Aiiiilic'ation October so, 1944',= Serial"No."5611184 2 Claims. (Cl.-280-.44) t This invention .Iappertains: to I new and useful improvements inawheel jacks and=more= particu- At present, it requires several men to remove s or apply heavy duty bus and truck wheels es- 3 :peciallylof. the dual type.

#The. principal object of theepresent-invention .-.."is-rt p1o\iide a wheel lift truck which-[can ne .readily setunder a heavyjduty -truck or bus-wheeh toLtheQ endthatthe wheel. can be elevated-after .sits fastening meansihave been, removed and .hahled 'away with but little-effort on thefipart of the workman.

Another important object of the invention is to provide a heavy wheel lift, which in itself is capable of being easily operated and which includes hydraulic means for lifting the elevator means thereof.

Other objects and advantages of the invention shall become apparent to the reader of the following description.

;- members; --|6:passing* through: the rear-- "ends :of the-bars 1 5 to pivota-lly connect the upper ends Referring to the drawings, wherein like numerals designate like parts, it can be seen that a horizontal body 5 is provided with upstanding side walls 6, 6 which at one end has an axle 1 disposed therethrough, this axle having wheels 8 at its outer end.

A slightly angularly formed bar 9 is provided at each side of the body 5 and has its lower end apertured to receive the corresponding endof the axle l. The intermediate portion of each of these bars 9 has a pivot member I0 disposed therethrough and also through the intermediate portion of a complemental bar H of like form,

A second axle I2 is disposed through slots 3 in the side walls 6 and the end portions of the axle |2 pass through openings in the lower ends of the bars II, this axle |2 having ground riding wheels M at the ends thereof. It is preferable that the slots l3 in the wall 6 be reinforced by bearing ledges on which the axle H can ride, as 'shown in Figure 3.

On the forward end of the body 5 is a hydraulic cylinder 2| on which is a hydraulic fluid reservoir 22 having a filler cap 23. An outlet pipe 23 extends from the cylinder 2| and this outlet is regulated by a valve 25. The pipe 24 extends and connects by a fitting 26 to a cross line 21 connected at its ends to the cylinders 28 of hydraulic units generally referred to by numeral 29. In the cylinders 28 pistons 30 operate and from the istons 30 members 3| project outwardly and are apertured .to receive the end portions of the axle I2. The cylinders 28 are suitably secured to the side walls 6.

'Legs 33 depend from the hydraulic cylinder 2| and rest on the body 5 and screws 32 are disposed upwardly through the body 5 and into the legs 33 to firmly secure the cylinder 2| and its reservoir 22 in place on the body.

As can be appreciated, the cylinder 2| contains a piston from which extends a piston rod 33. The piston rod 33' extends through a notch 34 in one side wall 6 and has the intermediate portion of a control lever 35 clamped thereto as at 36. A lug 31 rises from the body 5 and the lower end of the lever 35 is pivoted thereto as at 33. The upper end of the lever 35 has a handle 39. Obviously, in the operation of the mechanism, the release valve 25 is first closed after which the lever 35 is oscillated to operate the piston in the cylinder 2|, which forces fluid from the cylinder 2| to the units 29. This action forces the axle l2 rearwardly and elevates the crossed bars 9, lifting a dual wheel assembly A to a position where it can be transported to the desired location.

When it is desired to lower the bars l5, the valve 25 should be opened thus gradually bleeding the units 23.

In handling heavy duty single Wheels, which are apt to tip over on the bars l5, IS, the top flanges of the bars I are formed with sockets 40 at the rear ends thereof for receiving the lower ends of upstanding tubes 4|. Rods 42 are vertically slidable in these tubes 4| and have outwardly disposed portions 43 terminating in hooks or arcuate extensions 44 adapted to engage over the tire of a single wheel B. A set screw 45 is carried by each vertical tube 4| and adapted to be screwed in against the rods 42 to hold the same in adjusted position against a wheel to prevent tipping over of the same.

The tubes 4| may be provided with crossed brace members 46, 46 to adequately support the same in an upright position.

A handle construction 46 is provided at one end of the body 5 to permit a person to easily move the device from place to place.

While the fdregoingdescription sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.

Having described the invention, what is claimed as new is:

1. A wheel lift comprising a body, axles at each end of the body and having ground wheels journaled thereon, one of said axles being fixed and the other axle being slidable in the body relative to the fixed axle, an elevator, said elevator being adapted to support a heavy duty wheel unit, crossed raising elements supporting the elevator and having their lower ends pivoted to the axles, and hydraulic means for slidably actuating the second-named axle to efiect a raising and lowering of the elevator.

2. .A wheel lift comprising a body, wheels at one end of the body, an elevator, said elevator being adapted to support a heavy duty wheel unit, crossed raising elements for lifting and lowering the elevator an hydraulic means for effecting a raising action of the said crossed elements, an axle disposed through certain lower ends of the crossed elements and ground engaging wheels carried by the axle, said hydraulic means comprising a pair of hydraulic units, a manually operated pump unit, a connection between the pump unit and the hydraulic unit, said body having a guideway therein through which the axle is dis posed, said hydraulic units operating on said axle.
